- CIRCUIT-TERMINAL FOR FUSES;

SPECIFICATION forming part of Letters Patent N 0. 734,407, dated July21, 1903.

Application filed March 21, 1903. Serial No. 148,9?9. (No model.) i

To aZZ whom it may concern:

Be it known that I, LOUIS IV. DOWNEs, a resident of Providence, RhodeIsland, have invented a new and useful Improvement in Circuit-Terminalsfor Fuses, which invention is fully set forthin the followingspecification.

My invention relates to improvements in circuit-terminals in whichelectric fuses are removably mounted, and particularly to those havingtwo arms bearing against opposite sides of the metallic caps at the endsof the fuse.

My object is to provide means for preventing longitudinal or endwisemovements of the fuse in the terminals, at the same time assuringaccurate relative positioning and proper electrical contact between theparts. A further object is to provide such means with little, if any,addition to the ordinary cost of the terminals. I

The improvements constituting my invention will be more readilyunderstood by reference to the accompanying drawings, showing one formin which it may be embodied.

Figure 1 is a side'elevation. Fig. 2 is a front elevation, and Figs. 3and 4c are detail views'of parts of a terminal.

As shown in the 'd rawings,the terminal comprises two principal partsaconducting plate or bar 1 and a clip 2. The latter comprises twospring-arms 3 3, connected at their lower ends by a cross-piece 4,against the inner face of which one end of the conducting plate or bar 1bears. A screw 5, adapted to pass through and secure the terminal to asuitable base, such as a porcelain block, (not shown,)

passes through an opening in the cross-piece 4 and engages ascrew-threaded,opening in plate 1, clamping the parts firmly together.The clip is preferably made by bending a strip do not limit myself inthis respect,as the arms may be formed in any suitable way. At one edgeeach arm is provided with an inwardlyprojecting lug, ear, or finger '7,constituting a stop to prevent longitndin al or end wise mo vement ofthe fuse in one direction. Preferably these lugs are intregal with thearms, this being the most economical way of making them; but I do notlimit myself either as to the manner of formation or the location ofthese logs so long as they perform the intended function of limiting orpreventing movement of the fuse in the terminal. Furthermore, only one.arm 3 may be provided with a lug 7.

A circuit-wire or similar connection is adapted to be held in electricalcontact with plate 1 by a screw 8 and washer 9. A lng, ear, orprojection 10, struck out of the metal of plate 1, leaving an opening13, also serves to limit the movement and determine the position of thefuse in the terminal. Lug 10 may be used either alone or in conjunctionwith one or more lugs 7. For general use, however, I prefer to simplyuse one or more of the lugs 7.

The fuse 11 (shown in the drawings) is of the now well-known inclosedtype having metallic caps 12 12 at opposite ends, against which the armsof the clips bear in completing the circuit through the fuse.

WVhat I claim is 1. In a circuit-terminal for electric fuses, a

conductor plate or bar, a clip comprising two ing or preventinglongitudinal or endwise movement of the fuse in the terminal. 7 3. In acircuit-terminal for electric fuses, a

clip comprising two springarms between which one end of a fuse isadapted to engage, and an inwardly-pl'ojeating lug on one arm forlimiting or preventing longitudinal or endwise movement of the fuse inthe terminal.

4. In a circuit-terminal for electric fuses, a clip comprising twospringarms between which one end of a fuse is adapted to engage, aninWardly-projeeting lug on each arm for limiting or preventinglongitudinal or endto Wise movement of the fuse in the terminal.

In testimony whereof I have signed this specification in the presence oftwo subscribing Witnesses.

LOUIS \V. DOWVNES.
